IMPROVEMENT IN TRANSQM-LIFTERS.

Specification forming part of Letters Patent N 0. 188,947, dated March 27, 1877; application filed February 5, 1877.

To all whom it may concern Be it known that I, FRANK A. REIHER, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Transom-Lifters, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in transom -lifters on which Letters Patent No. 186,166 were granted to the undersigned, dated January 9, 1877 and these improvements consist in the peculiar c0nstruction of the rail attached to the transomsash; also, in the mode of operating the rack-rod, and in the arrangement of the parts in the casing, to adapt the same castings for right or left hand transoms.

In the drawings, Figure 1 shows a section of a door-frame and transom-sash with the improved transom-lifter affixed thereto. Fig. 2 shows the arrangement of the parts operating the rack-rod, the cover being removed. Fig. 3 is a vertical section to line 40 m of Fig. 2. Figs. 4 and 5 are cross-sections to line 3 3 of Fig. 2. Fig. 6 shows a plan view of the handle inverted. Fig. 7 shows the casing separate.

The transomsash A, hinged to the doorframe D in the usual manner, is provided with the slotted guide-rail M, and the arm 0, operating with the finger d in the slot a. of the guide-rail, adjusts the position of the transom in a similar manner to that shown in the patent referred to, by means of segment E and rack-rod F.

The slot 01. in guide-rail M is inclined to the sash A, and bends almost vertically toward the sash at the most elevated end a. The inclined position of the slot will allow a wider opening of the sash, the slot being nearest to the sash at its outer or end opposite the hinge.

When the transom-sash is closed, as shown in Fig. 1, the finger d of the arm 0 will onter the slot part a. The sash cannot be opened by pushing against its outer side, as such a pressure will cause the inside of the rail M to bear against the finger d. The rail is rigidly aifixed to the transom sash,

and the finger d and arm 0 will resist a direct pull. It will be seen that the transomsash is thus locked, and can be opened only by a swinging movement of the arm C. The slot part a, in conjunction with the finger d and arm C, forms a perfect and secure lock.

The rod F is provided at its lower end with another rack, f, gearing to the pinion segment K, which is made to turn with the pin 9 of the crank or handle G, all arranged in the casing H, as shown in Fig. 2. This casing (shown detached in Fig. 7) is made to answer for transom-lifters to be operated from the right or left hand side of the door; and to this end it is provided with two holes, I) and b, situated close together, so as to form one orifice, and these, with corresponding holes 0 and c in the cover-plate it, serve as a bearing for the pin 9.

For transoms to be operated from the lefthand side of the door the rack f, with pinionsegment K, is arranged as shown in Figs. 2 and 5. The pin 9 is centered in the holes I) and c. For transoms operated from the right-hand side of the door the rack f is inverted, and the pinion-segment K, with pin g, is centered in the holes I) and c, as shown in Fig. 4.

The pinion-segment K is provided with two recesses, i and i. The projection or beard n on pin gdrops into one of these recesses, and by its rotation carries the pinion with it. The projection n is situated under the cover h, in such a manner as to keep the pin g, with handle G, in proper place. These cannot be taken out after the cover is fastened to the casing.

The upper part of rack f, where it connects to the rod F, is made square, and its surface, above and below, is provided with a number of corrugations or small teeth, p. A little plate, q, provided with corresponding corrugations, is situated in a recess formed in the cover h, and, by means of the thumbsorew J, serves to hold the rack-rod F, and, consequently, the transom-sash, secure in any desired position.

It will be seen that one set of parts will answer alike for left or right hand transoms.

What I claim as my invention, and desire 3. The rack f, with its corrugated surfaces to secure by Letters Patent, isp p, in combination with the plate q and 1. The rail M, with slots (1 and a, acting in thumb-screw J, as and for the purgoses set conjunction with the arm 0 and finger d, for forth. the purpose set forth.

2. The combination of the rack f, pinion- FRANK REIHER' segment K, handle G, and pin 9 with the Witnesses:

casing H and cover h, all arranged as shown J. O. WELGKE, and described. J. C. RICHARDS.
